A transistor is generally used as a switching device or an amplifer... and has many many applications from audio ampliers, and radio transmitors/receivers, to the heart of computers (in the number of millions and even billions within IC's and micro controllers or microprocessors).

Transistors a usually 3 terminal devices (unless there cascaded- with a combination of other transistors). The 3 terminals are: Base, Collector, and Emitter. You can think of a transistor as a 2 terminal switch that is cotrolled by a 3rd terminal known as the Base -(for BJT's; Bipolar Junction Transistors, the most basic) the base is the input, and it controlls the current that flows between the Collector and Emitter
